Solution

Balanced chemical equation
1) The atoms of chlorine and hydrogen are balanced on product side by writing 2 as coefficient of HCl
BaCl₂ + H₂SO₄ → BaSO₄ + 2HCl

2) Firstly, to balance Chlorine atoms on reactant side, we write 4 as coefficient of HCl.
MnO₂ + 4HCl → MnCl₂ + H₂O + Cl₂
Now, to balance H atoms on product side, we write 2 as coefficient of H2O.
MnO₂ + 4HCl → MnCl₂ + 2H₂O + Cl₂
